Anti seizing

Depending on the application, I use one of three anti-seize compounds.
For anything going into aluminum Tef-Gel is the way to go. Expensive, but a little goes a long way. Don't purchase those silly little tubes, buy a tub much cheaper in the long run, http://amzn.to/2lHbkDf
For engine work, where temperature may be an issue Bostick's Never Seize Marine. Again, not cheap, but I'm still working on the can I bought 20 years ago. http://amzn.to/2lHtqTS
For turnbuckles and low stress fittings Lanocote works pretty well and it is very inexpensive. It is better for fittings that get moved from time to time such as rigging parts. Forespar Lanocote

I had been following the thread on deck/steaming light woes. Later, I was at the register at AutoZone where they had little Trojan-size (not the batteries) packets of various products. One was "Bulb Grease" by AGS, in MI. "Prevents corrosion, Moisture proofs, assures easy removal, seals and protects all electrical connects". 1.49 for .14 oz, .
Locktite makes three anti seize compounds composed of metals and graphite. Nickel (copper free so good on stainless) Copper and Aluminum. I use Nickel for exhaust parts, aluminum for just about anything else.. They also make another specific for stainless and titanium no metal in that recipe.
The compounds are not just for anti corrosion. They also protect from galling (think 'cold' welding) which is common in stainless and aluminum threaded fasteners and fittings.
Otherwise plain vanilla anhydrous lanolin from your local pharmacy.

I use this. https://www.mcmaster.com/#antiseize-lubricants/=16ihku4
McMaster Carr also has others if you search "anti-seize marine lubricants"

That stuff Charles mentions from never seize is made with a ceramic powder, and works well on everything!
I've been using Loctite 34026 (it also goes by is 8023). https://www.amazon.com/Loctite-34026-Marine-Anti-Seize-Bottle/dp/B000WXHGHA
It's non metallic, graphite based and very, very black. Wear old clothes when working with it. Did all my turnbuckles and keel bolts.

Didn't realize there were so many to choose from. I guess I better do a little more research. The guys at my marina use Lanocote on the Catalina rentals. I will give that a try but keep the others in the back of my mind. Thanks for the list of available products.
the standard for many years in aerospace for installing steel fasteners into aluminum is/was to use zinc chromate primer. I saw a study by P&W that to reduce environmental concerns they may have switched to TT-P-645B that eliminates the chrome but you can still buy the zinc chromate primer. I'd go with that if you can find a reasonable size container. You don't need a whole gallon and I don't recommend a spray can as overspray is a big waste.
No, that is not what the study said (and I would know).
Earlier phases tested winch grease and general purpose greases for corrosion protection and wash-off. A few of the winch greases did well, and several GP greases did even better. Originally, Lanicote and Tefgel were in the GP group, but they were separated for publication. However, Lanicote and Tefgel did NOT finish at the top of the class. They were very good, but not best.
Spoiler: This has not yet been published. The most notable failures were conductive greases that contain metals. The marine formulas are typically metals-free, but even well respected copper-loaded, graphite-loaded, or zinc-loaded versions did not do well in marine environments; they invited dissimilar metals corrosion problems far worse than any problems they solved. But you'll have to wait for the details in the conductive vs. dielectric debate. However, if there is salt around avoid ANY anti-seize that contains metal particles.
I currently have a battery of samples hanging under the dock such that they get wet only during spring tides, and then dry salty. At the 1-year mark (soon) I will test the break-out torque (SS screws in a mast section, and galv bolts in steel). I don't know what will be best. Green grease, Lanicote, Tefgel, and teflon pipe dope are have a lot going for them, and I have used all four with considerable success. There are also other products in the test. I would also be surprised if there were not two winners (Al/SS and Galv/steel). And high temp engine applications are NOT being tested.
Something else to be aware of. Some products (Tefgel and teflon pipe dope, for example) may reduce the ability of a bolt to stay tight. As Robert Heinlein popularized, "there aint' no such thing as a free lunch." Reduced contact means reduced friction, and that cuts both ways.
I've noticed the reduced friction and sometimes that is OK, but at other times not so much.
Perhaps that's why McMaster-Carr lists them as "anti-seize lubricants."
loctite brand nickle anti seize is the best for all applications where stainless steel fasteners are used that may have to be removed, but the loctite marine type antiseize is non metallic, so in some applications it may be better.... im not sure if all brands of marine antiseize are non metallic or not... but all nickle antiseize is formulated as an extremely high temp lubricant and to prevent stainless steel from galling.
I only use the nickle formulation...

Amen too.
Except if the materials are copper and copper (bronzes), aluminum threaded fittings (tanks), nickel for cast iron motor parts/iron fasteners) thus no relevant metal dissimilarities.
To the point - the metallic formulas are very effective (aluminum and nickel for example) for just about all motor component fasteners whereas TefGel, LaniCote and the like are quite disappointing for these assemblies. (Head bolts are an exception - follow manufacturer torque recommendations in that case.)
For threaded components above decks exposed to the weather - then Amen.

I've always assumed that was because at high temperature the organic portion will eventually turn into coal. As you say, high temperature is different, and the article clearly disclaimed the difference. One size seldom fits all.
